This invention relates to a bath aerating apparatus; and has for its object to provide in such an apparatus a rack member shaped to be placed in a bath tub to support the body of the bather, the rack having perforations thru which a bath treating gas such as air, carbonic acid or other suitable gas, is admit-ted under pressure to the bath water.`

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a side elevation partly in section showing one arrangement of my improved bath aerating'apparatus. t

Fig. 2 is a detail view partly in section of the rack for supporting the bather and admitting the bath-treating gas.

Fig. 3 is a cross section of a portion of the rack showing the air discharging openings located below the plane of the supporting surface of the rack, also showing the packing arranged to prevent the water from entering the gas channels in the rack.

Fig. 4 is a longitudinal section on line 4-4 of Fig. 3 showing a strip of packing as wedged in between the ribs over the discharge opening to prevent the bath water from entering the air openings inthe rack. t

F ig. 5 is a detail illustrating an air connecting nipple to which the rubber air tube may be readily connected.

Fig. 6 shows a detachable form of connecting nipple. i

Fig. 7 is a detail showing the bottom plate as connected 'to the body of the rack by means of screws passing upward therethru into threaded members imbedded in the rack body.

It is found in practice that an aerated bathV produces beneficial effects upon the bather, particularly on one who is of a nervous tempermanent as it serves to reduce blood pressure and rest the nerves and is generally refreshing to the bather. It is also found of advantage to heat the air before beingadmitted to the bath so as not to cool the water into which it is injected. Also in some instances, it is found especially pleasing to inject or admit a perfume into the air as it is being conducted to the bath, and to produce these advantages in a simple and effective way, I have provided an air-discharging rack which is shaped to iit into and rest upon the floor of the tub and is provided with a surface to comfortably 1928. Serial No. 276,587.

support the body of the bather and is also i r nates theusual form of bath tub in which may` be deposited a rack member 11 whichis herein shown as being of a size and shape to rest upon the floor of the tub. y This rack maybe constructed of any suitable material and is preferably formed with a body member having raised longitudinally-disposed broadfaced ribs 12 forming surfaces for the comfortable support ofthe body of the bather.

Between these ribs is formed longitudinally-disposed channels 13 each having a bottom wall or partition 1-1 below which is formed an air-conducting channel 15, and all of `these channels are connected together at one end by the cross channel 16, the supply of air or gas being admitted to this cross channel thru a nipple 17 fixed in the end wall 18 of the rack. This bottom wall 14 ofthe channel 13 is provided with spaced slots 18 against the inner portions of which rests a strip of packing 19 for the purpose of closing these slots against admission of bath water to the inner air channel to also obtain a better distribution of the air through the different slots and at the same time permit the discharge of air from the passageway 15 into the bath. In order to crowd this packing 19 closely against the inner ends of the discharge slots 14, I have provided ribs 20 spaced along yth air passageway 15 opposite the slots 18 an in order to condense the packing 19 against the discharge slot openings 18, I form an inclined surface 2l on the ribs 20, also an inclined surface in the side wall 22 of the air channel 15, whereby when the bottom plate 23 is forced into position by screws 24 this packing which is preferably of fibrous nature is condensed as forced to its seat to control the admission of water from the bat-h back into the air passageway 15.

lVhen air is used for treating the bath, I provide a pump 24 which is run by a motor 25, the air from the pump being forced thru pipe 26 and thru a coil 28 in an electric heater 27. Thence it passes thru pipe 29 which is connected to the nipple 17 of the air-distributing rack.

'Ihe temperature in the heater may be raised by any suitable means, that herein shown beingl eiected by resistance coils thru electroeirouit Wires 30 and 3l.

In some cases, it is found of advantage to be lable to inject perfume into the air supply pipe which is done by an inject-or member Which draws the perfume from a bottle 33 up thru pipe 34e, a valve 35 beingI provided for cont-rolling the amount ot' perfume which shall be drawn into the entrained. heated air.

I do not `Wish to be restricted to en'iploying` air :tor aerating the bath as any other suit able gas such as oxygen gas, carbonio acid gas or other suitable gas may vbe employed V'for this purpose.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege or' resorting to all the mechanical changes to Which the device is susceptible, the invention being defined and limited only by the terms ot the appended claims.

I claim:

l. In a bath aerating apparatus, a body member having air conducting channels therein, air outlet openings communicating,` with said channels, a finely divided material in said channels partially closing said openings, a body closing bottom plate, and means for forcing,l air into said channels through said finely divided material and out through said openings into the bath.

2. In a bath aerating` apparatus, a chainbered body member having a supporting top plate With air inlet openings therethrough, a straining material in the chamber below the top plate coyerinpg the inner ends oi? the openings, and a bottom plate 'tor said body positioned. to force the strainingI material against said openings.

3. In a bath aerating apparatus, a chambered body member having' a eupportinp,l top plate with grooves in its i'aee, the walls ot said grooves having` openings therethrough, a straining material in the chamber below the Wall of the groove arranged to cover the inner ends of the openings, and a bottom plate tor said body positioned to loree said material against said opening.

Ll. In a. bath aerating apparatus, a body member having air-conducting; channels 'therein and air distributing openings comniunicating W ith said channels, walls in said channels, each having an inclined surface, a straining material in said channel engaging,l said inclined Walls, and a bottom plate for said body positioned to force said material against said inclined Walls to compress and condense it over said openings.

In. testimony whereof I ailix my signature.
